BY m. 710% ATTORNEY Patented Feb. 6, 1934 UNITED STATES PATENT OFFICE 3 Claims.

This invention has for an object the provision of a novel device which will mechanically produce smoke rings such as any smoker can produce, with slight practice, by blowing smoke from his 5 open mouth by quick movements of his tongue.

A further object of the invention is to produce an inexpensive device which will perform the above described function efdciently and still be very simple in construction and require no experience to operate.

Another purpose of the invention is to provide a novel device which, because of the comparative low cost of production, may be employed in advertising various commodities used by smokers and yet distributed gratis.

Still another object of the invention is the provision of a device which when put to the use defined will produce many novel effects and thus be susceptible to use in games of many kinds.

Other objects of the invention will become more apparent as the specification progresses and the novelty of the device will be particularly pointed out in the appended claims.

In the drawing forming a part of this specification:

Figure 1 is a perspective view of the device showing a smoke ring which has just been expelled from the discharge end of the blower.

Figure 2 is a sectional view of the device show- 3() ing. the relation of its parts, the smoke expelling piston of which is shown in a slightly withdrawn position in dotted lines.

In the drawing the numeral 1 indicates a small cylinder, which may be constructed of cardboard or in fact almost any material, having one end completely opened and a vent 2 in the opposite end. The open end of the cylinder 1 is closed by a piston 3 slidable within the cylinder and yet in such a close fit as to prevent the escape of smoke from that end of the device.

The piston 3 has a rim 4, of slightly larger diameter than the cylinder 1, and projects outwardly above the cylinder wall in order that the same may be grasped between the fingers of the operator and a forward and backward movement of the piston within the cylinder obtained.

With this construction in mind, the operation of the device will be readily understood. The operator first withdraws the piston from the cylinder completely; seals the vent 2 by placing the palm of his hand or a finger thereover; places the open end of the cylinder to his lips and expells a puff of smoke into the cylinder. While still closing the vent 2, the cylinder is quickly taken away from the operator's lips and the piston inserted in the open end of the cylinder as far as it will go to prevent escape of the smoke.

To produce the smoke rings the operator first removes his hand or finger from the vent 2, and then grasps the piston by its rim 4 and withdraws it from the cylinder into the position shown in dotted lines in Figure 2. By quickly tapping or pushing the piston into the cylinder as far as it will go, a ring such as that shown in Figure 1 is produced. To continue the production of rings, this operation is repeated by simply withdrawing the piston and pushing and pulling it inwardly and outwardly with a quick backward and forward movement.

Experimentation has taught me that what actually happens when the device is thus operated is substantially as follows: When the cylinder has been filled with smoke and the piston withdrawn to substantially the position shown in dotted lines in Figure 2, a current of air rushes into the cylinder through the vent 2. This is because the cubical content of the cylinder has been thus increased. When the cylinder or rather the piston is quickly thrust to its innermost position, the smoke, being lighter than the air within the cyl-' inder, is expelled. The amount of smokethus expelled corresponds to the amount of air drawn into the cylinder by the withdrawal of the piston from the cylinder into the position shown by dotted lines in Figure 2 of the drawing.

The smoke rings are produced or rather result from the expelled smoke striking the ends of the cylinder 1 and being forced to escape through a vent smaller than the diameter of the cylinder.

By experimenting with this device, I have found that very novel effects can be produced. For example, in a still room, free from drafts or currents of air, I have found it possible to first produce one ring and by a slightly longer and quicker stroke of the piston, expel a second ring through the first. This one result has convinced me that the invention has a great many possibilities in that it can be used in a great many ways. Thus I have found that the novelty may be used in four or five games such as would be played at the average party attended by those at the smoking age, and it is unquestionably adaptable to many more.

It must be appreciated, of course, that this device is subject to many modifications and variations of the form shown in the accompanying drawing. For example, I have found that the main chamber, here illustrated as the cylinder 1, need not be cylindrical at all, but may be rectangular in form, and it will still produce the desired result. Similarly, I have found that the vent 2 need not be a round hole but on the contrary the same results will be produced with a hole of almost any shape. For these reasons I do not wish to be limited to the form shown in the accompanying drawing, but rather desire protection to the extent of the appended claims.

Having thus described my invention, what I claim and desire to secure by grant of Letters Patent is as follows:

1. A device for blowing smoke rings comprising, a cylinder having a restricted vent, a piston slidably mounted in the end of said cylinder opposite said vent, said piston having a flange of greater diameter than said cylinder.

2. A device for blowing smoke rings comprising, a cylinder having a. restricted vent, a piston slidably mounted in the end of said cylinder opposite said vent, said piston having a flange at the butt end thereof of greater diameter than said cylinder.

3. A device for blowing smoke rings comprising, a cylinder having a restricted vent, a piston slidably mounted in the end of said cylinder opposite said vent, said piston having a flange at its butt end of greater diameter than said cylinder whereby said piston may be readily grasped and pulled outwardly and pushed inwardly to create air impulses within said cylinder.
